Mortality rates of the common sole Solea solea from Alexandria were estimatedbased on the von Bertalanffy growth parameters obtained by the same authors as L∞= 34.77cm; K= 0.55 year−1 and t0 = 0.07 years for males, L∞ = 36.24 cm; K= 0.63year−1, t0 = -0.01 years for females and L∞ =35.1 cm; K= 0.58 year−1 and t0 = 0.003years for sexes combined during two fishing seasons (2011-2013). The total, naturaland fishing mortalities were 2.09, 0.52 and 1.57 year−1 respectively for males, 1.75,0.53 and 1.22 year−1 respectively for females and 1.7, 0.52 and 1.18 year−1respectively for sexes combined. Correspondingly, the exploitation ratio was E =0.75, 0.7 and 0.69/y for males, females and sexes combined respectively. Theestimated length at first capture Lc was 15.97, 12.72 and 14.22 cm for males, femalesand sexes combined, respectively while the length at first maturity Lm was 15.31,15.87 and 15.98 cm for males, females and sexes combined, respectively. Theseresults reflect the high level of the exploitation. The relative yield per recruit analysisshowed that the stock of S. solea is over exploited and needs urgent managementregulations to conserve this potential fishery.
